CHARLES L. COOKSON, OF KANSAS CITY, MISSOURI, ASSIGNOR TO ADMIRAL HAYPRESS COMPANY, OF KANSAS CITY, MISSOURI, A CORPORATION OF MISSOURI.

BALING-PRESS.

T (ZZZ whom it may concern:

Be it known that 1, CHARLES L. CooitsoN, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Baling- Presses, ofwhich the following is a specification.

This invention relates to baling presses and has for its object toproduce a machine of this character having a longer stroke and capableof exerting greater power in such stroke than machines of the samegeneral character and length.

Another object is to produce a baling press provided with mechanismwhereby the maximum power which could be applied directly by the pitmanon the baling material is increased on the latter at a loss of speed onthe part of the plunger or head block.

Another object is to produce a baling press having an automaticallyoperating feeder and means whereby the power of the operative stroke ofthe feeder is increased as the resistance offered to the feeder by thebaling material is increased by the compact ing or condensing of thelatter in the baling chamber.

With these general objects in view the invention consists in certainnovel and peculiar features of construction and organization ashereinafter described and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which Figure 1,is a side elevation of a part of a baling press embodying my invention.Fig. 2. is an enlarged central vertical longitudinal section of a partof the press. Fig. 8, is a section on the line IIIIII of Fig. 2. Fig. isa section on the line IV-IV of Fig. 2 with part of the crank shaft mechanism in elevation. Fig. 5, is a central vertical longitudinal section ofa part of a press embodying certain changes of construction from thepress shown in the preceding figures. Fig. 6, is a similar view but withthe plunger at the beginning instead of at the end of its stroke as inFig. 5. Fig. 7, is a vertical transverse section on the line VII-VII ofFig. 6. Fig. 8, is a detail perspective view of one member of the pinionsegment shown on Sheets 4 to 6 inclusive.

The frame 1 of the press is of the customary construction as shown and 2incli- Specification of Letters Patent.

cates the usual hopper and 3 the reciprocatory head block or plunger.

4 is a shaft adapted to be driven by an engine or belt and provided witha pair of pinions 5meshing with the large gear wheels 6 journal-ed inthe frame of the machine and connected together by a cross pin 7 whichpin in conjunction with the wheels 6 constitute a crank connectedpivotally by a pitman 8 with agear toothed pinion 9, the connect-ionbeing out-ward of the center of the pinion for a purpose whichhereinafter appears, and said pinion engages a rack bar 10 extendinglongitudinally of and rigid with the frame. In Figs. 1 to 1 inclusive,the apron 11 of the head block or plunger operates above said rack barand between the sides of the frame, as shown clearly in Fig. 2.

Underlying and engaging the pinion 9 is a rack bar 12 adapted to travellongitudinally upon the bottom of the baling case and mounted at itsrear end upon a pair of rollers 13 and pivotally connected at its frontend to the head block or plunger by a pin 14.

15 are standards mounted upon the frame and forming a support andjournal for a transverse shaft 16, and mounted pivotally upon said shaftbetween the ends of the spacing sleeve 17 thereon and said standards 15,is a pair of swing arms 18, connected at their outer ends by a cross pin19.

20 is a pair of links pivotally connecting cross pin 19 with rack bar12, at opposite sides of the pinion 9 for the purpose of impartingrocking movement to arms 18 and a pair of levers 21 which are pivoted oncross pin 19, and rest on sleeve 17 and pivotally carry at their frontends a presser foot 22 for forcing baling material from the hopper intothe baling chamber, the upper end of the hopper being notched at 23 toaccommodate the levers 21.

2a is a clamp plate bridging the space between levers 21 and restingupon the upper edges of the same, and is aspring for causing said plate24 to hold the levers 21 pressed yieldingly against the sleeve 17 thespring being held in position by means of a bolt 26, which extendsthrough plate 25 and a similar plate 27 bridging the space between andhearing at its end upwardly against arms 18, a washer and a nut 29fitting on the upper end of the bolt and holding the spring undertension.

To maintain the presser foot in a substantially vertical positionthroughout its entire travel in feeding hay from the hopper into thebaling chamber and in withdrawing to position above the hopper, Iprovide apair of links which pivotally connect the upper end of thepresser foot with the upper ends of the standards 15.

In Sheets 1-, 5 and 6, parts identical in construction and function withparts of Sheets 1 to 3 inclusive, are correspondingly numbered. In saidSheets 4: to 6 inclusive, 1 use a pinion segment 31 in place of the gearpinion and axially of the said segment it is provided with a transverseshaft 32 which extends thrcugh longitudinal slots 33 in the side wallsof the baling case and is equipped at its ends with rollers 34 travelingupon and between pairs of spaced tracks and 36 secured externally to thebaling case, it being noted in this connection that the pinionmentconsists of two members correspondingly numbered and that there is apair of fixed overlying rack bars 37 cast or otherwise rigidly formedwith the bridge plate 38 mounted on the sides of the frame and forming asubstitute for the single rack bar 10 of Sheets 1 to 3 inclusive. InSheets 4 to 6 inclusive, the head block of the plunger is also providedwith extension sides 39 fitting against the inner side of the balingchamber and provided with short longitudinal slots 4:0 wherein travelflanged rollers ll journaled upon the shaft 32 and forming a means toguard against tilting of the head block of the plunger. The pitman Spivotally connected at one end to crank 7, is pivotally connected at 42to the pinion segment, and the latter is also pivotally connected at 1:3by a link ist with the head block or plunger at to, itbeing noted thatradial planes intersecting the axis of the pinion segment from pivots t2and extend at an angle to each other. The feeder mechanism for forcingbaling material from the hopper into the baling chamber in advance ofthe head block or plunger corresponds substantially to that shown inSheets 1 to 3 inclusive. its in the former sheets, 15 indicates thestandards extending upward from the baling case and 16 the transverseshaft ournaled in said standards. 16 is a casting journaled on saidshaft and provided with a pair of arms l? pivotally connected at as to alink 19 pivotally connected to the pinion segment 31 at as distinguishedfrom the links 20 which are pivotally connected to the reciprocatoryrack bar 12. 21 are levers pivotally connected at 128 to arms 17 andalso connected to the presser foot 22 as in Sheets 1 to 3 inelusive, andsaid levers 21 are held pressed flatly against the casting 16 by clampplate 24; through the instrumentality of a spring 25, a rod 26 extendingthrough said plate 2% and casting 16 and said spring and a washer 28 andnut 29 engaging the upper end of the spring and rod respectively, and tomaintain the presser foot in substantially vertical position it ispivotally connected as hereinbefore explained to the standards 15 by thelinks 30.

Referring first to the operation. of the construction shown in Sheets 1to inclusive, and assuming that the feeder is elevated, the head blockor plunger is advanced, and the crank is being turned in the directionindicated by the arrow Fig. 1, it will be seen that the pitman is aboutto startin the direction indicated by the adjacent arrow, and henceutilize the pinion 9 as a lever fulcrumed. at its upper side on rack bar10, to effect withdrawing movement of rack bar 12 and the head block orplunger and down ward movement of the feeder. The initial. part of thewithdrawal mov ment of the head block or plunger is relatively slow butincreases rapidly owing to the fact that the leverage decreases as thepivotal point of connection between the pitman and 'he pinion graduallyapproaches nearer to the fulcrum point, that is to say movesconvergingly upward with respect to the end of the rack bar remote fromthe hopper, and in this connection it will be apparent that owing to thegradual increase in speed of the with drawal movement of the plunger,the downward movement of the feeder likewise becomes more rapid andhence more eifective in overcoming resistance of the baling material, asthe latter becomes closely bunched in the baling chamber, as will bereadily under-- stood by reference to Fig. 2, which figure also showsthat the head block or plunger has nearly completed its withdrawalstroke before the lower end of the feeder passes from the hopper intothe baling chamber, and for this reason there is no chance of conflictbetween the head block or plunger and the feeder. At the end of a halfrevolution of the crank, the latter in the position shown in Fig. 2, sothat as its rotation continues, the initial advance movement of the headblock or plunger and upward move ment of the feeder is very rapid owingto the long leverage which the pinion 9, has on the rack bar 12. Thisrapid preliminary move ment of the head block or plunger is desirablebecause it occurs when the baling mate rial is loose and offers butlittle resistance and when the least power or force is required. As thehead block or plunger is advanced the leverage thereon is diminished bydiverging movement of the pivotal point of connection of the pitman withthe pinion from the said remote end of the rack bar 10, and as the firstrevolution of the crank is completed the advance movement of the headblock or plunger is slow but powerful, owing to the fact that thepivotal point of connection between the pitman and the pinion 9 is veryclose to the point where said pinion applies its power on the rack bar12. It will be obvious that the upward movement of the feeder diminishesin speed as the advance of the plunger slows down, owing to the factthatthe said elements are linked together.

Referring now to Sheets 4 to 6 inclusive, in which the crank of courseoperates in the same direction as in Sheets 1 to 3 inclusive, it isdesired to call attention to two features of construction which inprinciple are be lieved to be the same as in Sheets 1 to 3 inclusive butwhich are believed to possess advantages not possessed by the lattertype of construction. The construction shown by Sheets 4 to 6 inclusiveprovides for more powerful compression at the extreme end of the advancestroke of the plunger and thus produces more compact bale, and owing tothe connection of the feeder with the pinion segment instead of with thehead block or plunger, the leverage on the feeder is increased at thetime when power is most required, namely at the moment the feeder entersthe baling case, when it is desirable that the baling material shall becondensed to the greatest extent as by giving the feeder additionalpower at such time, larger charges of baling material may be introducedwithin the hopper and the entire operation of baling be therebyfacilitated.

Referring now in detail to the operation of the construction shown bySheets 4 to 6 inclusive, it will be seen that as the crank movesdownward from the horizontal position shown in Fig. 5, it exerts a pullon the pinion segment 31 whereby the latter swings on the rack bars 37as a fulcrum, and begins to withdraw the head block or plunger, throughthe instrumentality of the link 44, and the feeder is caused to descendthrough the connections between the same and the segment, continuedmovement of the pitman resulting in its pivot 42 traveling diagonallyupward toward the end of the rack bars remote from the hopper, andthereby diminishing the leverage on the crank of the segment andeffecting an'increase in the speed of withdrawal movement of the headblock or plunger and the descending movement of the feeder. It will benoticed, however, that owing to the fact that the pivotal point 50 movescontinually nearer to the fulcrum or rack bar on which the segmenttravels, the leverage on the feeder is increased and its speed ofdownward movement is proportionately diminished so that its maximumpower is available for efiecting the greatest possible condensation ofthe baling material in the baling chamber in advance of the head blockor plunger. As the rotation of the crank continues from the positionshown in Fig. 6, the pinion segment swings under the pressure of pitman8 and imparts rapid advance movement to the head block or plunger andupward movement to the feeder, the movement of the latter beingrelatively slow but sufficiently rapid to avoid conflict with theadvancing head block or plunger. When the plunger has made somethingmore than half of its advance stroke, the crank 7 pivot 42, pivot 43 andpivot 45 are alined, and at that moment the pressure of the head blockor plunger on the baling material is equal to that imposed by the crankon the pitman. Under the remainder of the second half revolution of thecrank, the parts move from the position shown in dotted lines Fig. 6, tothe position shown in full lines Fig. 5, in which latter position itwill be noticed that pivot 43 is above the plane occupied by pivots 7and 42 and the inclined plane occupied by pivots 42 and 45, and thatthis final movement of the head block or plunger oc curs with themaximum power developed by the machine, that is with a greater powerthan that which is imposed by the crank when the four pivots mentionedare alined as shown in dotted lines Fig. 6, it being understood thatthis extra or excess power is of course obtained by a decrease in thespeed of the advance movement of the plunger. It will be understood thatthe segment when it has attained the position shown by dotted lines Fig.6constitutes one member of a toggle of which the link 44 constitutes theother member, and that after the parts have attained the positionmentioned, the crank 7 utilizes the segment as a long lever fulcrumed onthe rack-bar tooth nearest the head-block or plunger, for expanding saidtoggle and thereby efiecting advance moveaent of the hea d-block orplunger from the said dotted position to the position shown in Fig. 5.By thus straightening or expanding the toggle after the application ofdirect power by the crank upon the head block or plunger ceases, as whenthe parts are in the position shown by dotted lines Fig. 6, a compoundleverage is obtained whereby the baling material is compressed togreater density than is possible by any direct application of power fromthe crank.

From the above description it will be apparent that I have produced abaling press embodying the features of advantage enumerated as desirableand 1 wish it to be understood that while 1 have illustrated anddescribed the preferred embodiment of the invention I reserve the rightto make all changes falling within the spirit and scope of the appendedclaims.
